ROAD ANDSTRET CUTTER.

Applicationled September 30, 1921; Serial No.n 504,424;

To all whom t may concern:

Be it .known that lf, Annett-mi ZiLBnnsHnii,.

acitizen of the United States, anda resident of thefcity of New York, borough of Manhattan7 in the county and `State of New,

York, have invented a new and improved Road and Street Cutter, of which the following is a full, clear, and exact description.

rThis invention relates to cutting devices for roadways and has for an object to provide an improved construction wherein the roadway may be cut into small sections so as to have the surface easily removed.

Another object oit the invention isy to provide a cutter for asphalt roadways wherein a structure is presented which will readily out the roadbed when pressed by av roller or other weight, the arrangement being such that the cutter may be readily removed alf-ter the cutting operation.

[i still further object of the invention is to provide an improved cutter for cutting the surface ot roadways at points where the same is to be repaired, the arrangement being such that the cutter will substantially. lit over the surface to be removed and when pressed will cut the surface into'small'sections tor easy removal.

ln the accompanying drawings* Figure l is a` fragmentary sectionalview.

through a roadway on which is mounted a cutter disclosing one embodiment ofvl the in vention together` with a roller and guide` therefor.

Figure 2 is a view similar to Figure l but showing the roller after itr has substantially passed over the cutter.

Figure 3 is a view similar to Figure l but showing the parts in an operated position with the weight resting on the cutter.

Figure 4: is a view similar to Figure 3 but showing in action the roller'wheny pulling the cutter out of the roadway.

Figure 5 is a top plan view ot" the construction illustrated in Figure l.

Figure 6 is a transverse sectional view through Figure 5 on line (f3-6.

Figure 7 is a view similar toFigure 3 but showing the weightv elevated and the parts ready to rel-.ease the weight.

Figure 8 is a view similar to Figure 64 and is to be hereinafter referred to.

Referring to the accompanying drawings by numeral, l indicates a: roadbed ot any kind. tor instance, a roadbed coveredvwith asphalt. Roadways of' this kind and also other formsofroadway oftenY need repairing in spots and the practice heretofore has been to usea picle in digging up the oldfasphalt oipothercoating and-then` providing a new' Sometimes a.I burner hasfbeen used coating. tori burning o asphaltf for repair Work but@ this is-rather slow anch more or less-ex pensive.`

v In the present invention,y ai construction- 1sprovidedf which willi quickly and easily cut into small sections eithera` large or small section. of roadway sowthat: it may be either removed by a piel;Y or` other ineansl anch a new coating supplied. In order toV carry` out.` this intentiongi. cutterQ is providedowhich is shown as being divided into seetionsandl.' It( the place to be cut outis largea numberI of the cuttersfQ are arranged' in line and: aa suitable rollerv 5 passedlthereover. It desired'7 seine other. form ot'fweight y may. be used though an` ordinary steamV roller is very satisfactory.. However, in orderthatfthefsteamroller 5 shall easily/movev on to` theiupper surtace of the cutteifQ, an

inclined wedge `memlo er G i is 1 provided whichmay be of; wood orf/othermaterial and 'which is provided with one or more hooks adapted to. fit-.into suitable openings: 28 in the cutterA 2 so that the cutter will not move away from' the wedge as` the rollerj moves thereon but will move directly downward' same to enter the concrete any furtherv than the depth.` of the various'teeth 8; In.' order to cause the cutter to penetrate or cutr the asphalt coveringY fromy the top-to the bottom; a weight `9 is providedwhich is dropped one or a lar-ge number of' times onto the cutter 2. 'llhe operation of dropping the weight on the cutter is maintained until preferably the cutter hasassuined thev position shown in Figure 3. As the cutter is torced'into the:u asphalt or other surfacing matter, it is naturally tightly wedged vinto the surfacev and, consequently, it will' aie more or lessl difficult to remove manually; However, a chain or .other connecting meinber 29, is secured tothe rolleriii any suitable Inanner into* suitable rings l!) connected with thecutter 2;' The'rnller is' then backed 0E as shown in Figure -t andthe i oe respective sections of the roller are succes sively pulled out oi' the roadbed. It will be noted that the sections 3 and l are hinged together at 1l so as to maire tivo sections, but it desired, the device could be made solid or could be made into more than tvvo sections.

The section 4- is preferably made into a number of short sections or links which may be hinged as at 12, The forward or end links ot the respective parts et section 4t are connected together by a liront eres-s 13 whereby they Will remain in alignment With the various parts of section 3, said section 3 being preferably connect-ed by a cross bar `11i in which the apertures lS are provided. ln this Way, the short links are pulled out first and finally the section 3 1s removed When the roller is backed off as shown in Figure 4:.

ln regard to the weight 9 and the Way it opera-tes, it is intended that the Weight shall be automatically operated during the hammering or droppingaction. lVhen the roller is lirst brought into use, the parts are arranged as shown in Figure 1 With the Weight elevated and held in an elevated position by the short chain 15 hooked into the chain 22. The drum 16 is loosely mounted on a stub shaft 1?' secured to the roller in any desired manner. As the drum is loosely mounted on .the stub shaft the rotation thereof Will not atleet the drum or the chain 22. A ratchet Wheel 18 is rigidly secured to the drum 15 and co-acts with a spring pressed payvl 19, said paul being pivotaly mounted on to the rota-ting drums oiz the roller 5. `After the roller 5 has been moved to the position shown in Figure 2, member 6 Will ybe removed and the rollerI moved back to the position shown in Figure 7, after Which, the paWl 19 is manually released but is not connected to the restraining chain 20. As the roller 5 is moved backward, it Will cause the drum 16 to rotate and Wind up the chain so as to elevate the Weight. TW hen the Weight has been elevated to the proper extent, the hook at the end ci chainl is engaged with the chain 10 as shown .in Figure 1 and the Weight again brought to a position over the cutter.

`chain 15 is manually released and the Weight allowed to drop. This operation continues as often as may be necessary to drive the cutter into the roadbed shown in Figure 3.

As an alternative Way ol raising and lowering the Weight, the parts are caused to assume theposition shown in ligure 3 .and the. pawl 19 is released. its the roller moves back the paivl will merely pass around the ratchet Wheel 418 and unwind part of chain t vvill he noted tiet as the roller moves backivardly the paivl Vwill merely slip over the 'teeth or' ratehet Wheel 18 but when the roller is reversed and is moved toward the weight, 'the paivl will engage one oi the teetl of the ratchet Wheel and Will rotate the drinn `whereupon the weight `will be elevated and the parts will be in the position shown in Figure 7 When the ratchet Wheel 18 has made one revolution. lf desired the pawl 19 can be manually released at tais time, but it is pre-terrible to have a pin Q1 secured to a stationary part oij the relier 5, and which projects in the path ot movement ot the outer end oi the payvl, and when the pawl reaches the second pin 21 it is depressed, and swings its forward end "from engagement with the ratchet 1S. rllhis will cause the Weight to drop and the drum to unwind so that the parts Will be substantially in the position shown in Figure rlie roller is backed oil second time and the operation repeated. rlhis operation may be repeated as often as necessary. Vilhen this operation has been completed, the Weight is elevated and the chain 15 positioned as shown in Figure 1p v@neer more chains 22 are vthen connected with suitable hoolrs .3 and with the links or :ings 11 so that when the roller has movedI as shown in Figure l the cutter Will be pulled out oi the roadbed. lt is, of course, evident that the teeth .8, see Figures 6 and 8, ci the cutter may be short or long as desired so as to cut only the upper surface oi the rcadbed or cut entirely through the base t the roadbed.

The cutter has been shorvnas a square structure but it `will be evident that it may be round or ot some other shape without departing from the spirit ofthe invention.`v

lli-'ter the cutter has been removed shown in Figure d, the cut part of the asphalt may be readily removed and a new supply provided and rolled in place ir" desired. ilso, it desired, a metal boxing might be arranged in the depression or opening caused by the cutter tand the asphalt placed therein and pressed doivn to an even thickness. When this has been done the boxing is removed betere the asphalt completely sets and a nal rolling is provided ier causing the nevi asphalt to adhere to the Walls of the old.
